Division of a millimeter-sized and compartmentalized fatty acid droplet is triggered by a chemical pH clock reaction operating on the ten-second time scale. The autonomous pH change inside the compartment translates into the deprotonation of the fatty acid molecules, leading to a negative interfacial tension at the water-oil interface inside the droplet. This phenomenon induces the expansion of the droplet, which is followed by its division into daughter droplets governed by the Plateau-Rayleigh instability.
毫米级和分隔的脂肪酸液滴的分裂是由在十秒时间尺度上运行的化学 pH 时钟反应触发的。隔室内的自主 pH 变化转化为脂肪酸分子的去质子化，导致液滴内水-油界面的负界面张力。这种现象诱导液滴膨胀，随后液滴分裂为受 Plateau-Rayleigh 不稳定性控制的子液滴。
